a lication filed my 20, 1913. Serial No. 768.827.

To all whom it may concern Be it known that I, LOUIS J. Pnnnnzs, a citizen of the United States, residing at Lewiston, in the count of Nez. Peroe and State of Idaho, have invented a new and useful Explosive-EnginerPriming Mechaengine, the 'fuel for. atomization being brought from the carburetor float chamber and atomized either through the instrumeir tality 0t air under. pressure or through an atomizingbulb or pump, there being. provided manually controlled valves, one for each cylinder, for operation to connect the atomizing pipe for. communication with the cylinder.

'A further object of the present invention is the provision of manually controlled means for operating the valves to the atomizing device and to either the compressed supply or atomizing bulb or pump. 7

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter. described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing. from the spirit of the invention.

In the drawings Figure 1 is a side elevation of an explosion engine equipped with the present invention. Fig. 2 is an end elevation showing the method of connecting the atomizer to the carbureter. Figs. 3, 4, 5 and 6 are detail views of. the various parts of the priming mechanism.

Referring to the drawings, the numeral 1 designates the explosion motor or engine, which in the present instance is shown as a four-cylinder type, two cylinders of which vided with a single introduction port 5. The nipple 2, which as before stated is interchangeable with the nipple 2 is provided with the three ports 4 and 4. which are disposed at the proper time to be placed in registration with the three ports 5 and 5 of the valve 3, so that when the priming charge is admitted through the ports .3"-4. anv air pressure. within the cylinder will. hr hausted through the ports alt 21s clear-2y illustrated in Fig. 5. in order to operate all of the respective valves 3 or 3. eachis provided with a handle I which is operably connected to the siidable rod 6 provided with a handie 7. said rod being piojected through the dash-board 8 so as to be in ready access to the cbaufieur.

Led to each one of the nipples and connected to the reduced portions 9 thereof, are thel'lexible conduits or tubes 10, one to each cylinder. the opposite end of said tubes being connected in the dome ll of the atomiziug chamber 12. This chamber 12 is supported from the float chamber 13 of the curbureter. A. tube 14 is disposed in the wall of the carburetor and has its inlet end 15 projected into the fuel within the float chamber 13 while its nozzle end 16 is projected concentrically of the atomizing chainher 12 and in line to receive a streuni of air from the air induction no-zzie 13 of the pipe 18.

duction of air through the-conduit 18, the compressed air tank 19 is provided, a pipe 20 being led therefrom and through the valve casing 21 to tbe conduit- 18. The valve casing 21, as clearly illustrated in Fig. 6, is provided with the valve 22 having the two ports 22" for registration with the conduits 20 and 18. and with the conduits 23 and 18, said conduit 23 being extended through the dash-board 8 and provided with the manually controlled air supplying means, 24, .which may be either a hand pump or a bulb.

In order to operate the valve 22, a handle 25 is connected theret a rod 26 being connected to the handle and extended through thedash board 8 adjacent the air supplying means 24, the knob 27 being mounted upon the outer end of the rod to permit of the ready manipulation thereof. By means of the rod 26, the valve 22 may be operated to select either the air from the tank 19 or the air supplied bythe device 24. Mounted the atomizing pipe 14 is a. valve 28, whose In order to provide for the pro or intro to the cylinders of the engine.

handle '29 is operably connected to the rod 30,. said rod being normally held to close the valve by means of the spring 31. In order that the valve 28 may be operated coincident with the valves 33 when the rod 6 is pulled upon, a lever 32 is pivoted to the dash board as at 33 and has its upper end disposed to be engaged by the pin 34 upon the rod 6, and its lower end operably connected at 35 to the rod 30. It will thus be seen that when the rod 6 is pulled upon, the upper end of the lever 32 will be moved toward the dash board 8, while the lower end will cause the rod 30 to be pushed outwardly and thus operate the handle 29 to open the valve 28.

From the foregoing description, it is evident that by connecting the atomizing nozzle 14 directly with the carburetor, that the fuel is always at hand to be properly atomized through the nozzle end 16 thereof and into the dome ll of the atomizing casing 12, from Where it is distributed through the conduits l0 tothe various valved nipples connected By this means instead of injecting into the cylindersfthe liquid fuel directly, the effect ofthe air upon the atomized fuel will produce the desired carbureted air, which when introduced into the cylinders, will be more readily exploded, when the ignition system is actuated as is the usual custom to produce the spark within the cylinders.

It is evident that an apparatus installed and arranged as the present one, the liquid is readily atomized within the cylinders, and that the usual cranking of the explosion engine is overcome, as it is -simply necessary to operate the rods 6 and 26, when air pres sure is within the tank 19, to cause the proper atomization of the carbureted air into the respective cylinders. If desired. when tne air pressure has been decreased sufliciently to render the atomization insuflicient, the valve 36 may be closed and the pump 24 operated to produce the necessary air pressure for atomization, or the hand pump 24 may be used entirely. What is claimed is:

1. The combination with an explosive engine, and the fuel chamber of a carburetor, of an atomizing priming mechanism connected to supply carbureted air from the chamber of the carbureter to the cylinder of the engine, said mechanism including a conduit provided with a nozzle and led from the .fuel chamber of the carbureter, an atomizing and air receiving chamber surrounding the' nozzle, a conduit led from the chamber to the cylinder of the engine, an air supplying conduit led into the atomizin chamber in atomizing relation to the fue nozzle, a manually opened valve mounted in the conduit leading to the cylinder, 21 manually controlled valve in the air supplying conduit, an air pressure tank in communication with the air supply conduit, and a manually controlled pumping device operably connected to the air supplying conduit, the air controlling valve being dis- .posed selectively for connecting the tank or the manually controlled air supplying device to the air conduit.

2. A priming mechanism for explosive enines, including the float chamber of a car ureter, a conduithaving a nozzle in communication with the Heat chamber, an air receiving and atomizing chamber surrounding the nozzle thereof, a valve in said conduit, a conduit led from the atomizing chamher to the cylinder of an explosion engine, a valve in said conduit, an air supplying conduit led to the atomizing chamber, means for operating coincidently the valve of the 'atomizing conduit and the valve of the conduit led to the cylinder, an air pressure supply connected to the air supplying condult, a manually controlled supplying device connected to said conduit, and a manually controlled valve for selectively connecting the air supply pressure device or the manually operated air supplying device to the conduit.

In testimony that I claim the foregoing as my own, I have hereto afiixed my signature in the presence of two witnesses.
